Shot my 1895 Marlin using the RCBS 325 U and the Lyman 457193. At 200 yards I quickly discovered that the lighter bullet was just as accurate as the RCBS 325...so I compiled some Chronograph statistics using it. My target was a 2 lb coffee can (4.5 x 6.5") on a cable at 200 yards. I hit it more than I missed it after I zeroed it in.

Was wondering if any others have did this with theirs and would care to comment? All loads were mild in pressures. I did not up the powder charges, as from the chart, there is little velocity gain when increasing them. Going from 14 to 15 grains of Red Dot--yielded a measly 26 FPS.
